BACKGROUND OF THE INVENTION

Field of the Invention

The field of the invention is data processing, or, more specifically, methods, apparatus, and products for managing computing devices in a computing system and in a datacenter.

Description of Related Art

Modern computing systems can include many computing devices. The identity of the computing devices, the relative location of each computing device, and the location of each computing device within the computing system and datacenter are frequently unknown to each other and even unknown to system management modules, services, and servers. The relative location of each computing device and the location of each computing device within the computing system, however, can impact how each computing device operates. As such, the relative location of each computing device and the location of each computing device within the computing system can impact overall system performance.

SUMMARY OF THE INVENTION

Methods, apparatuses, and products for managing computing devices in a computing system, including: receiving image data from a plurality of image sensors, each image sensor coupled to a computing device in a computing system, wherein multiple computing devices in the computing system are coupled to multiple image sensors; identifying, in dependence upon the image data from the plurality of image sensors, one or more characteristics of the computing system; and initiating, in dependence upon the one or more characteristics of the computing system, one or more desired system management actions. Multiple images received from multiple sensors may be collated to virtually create an overall picture of the datacenter. Each image sensor and the associated devices may be known to each other. Therefore, once the images are collated, all the device locations in the datacenter may be identified relative to each other in the overall picture as well as in an X,Y,Z coordinate plane of the datacenter, therefore simplifying or enabling the systems management tasks such as inventorying, physical security, and thermal profiling.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

Example methods, apparatus, and products for managing computing devices in a computing system in accordance with the present invention are described with reference to the accompanying drawings, beginning with FIG. 1. FIG. 1 sets forth a diagram of an example computing system (102) in which computing devices are managed according to embodiments of the present invention. The computing system (102) of FIG. 1 includes a plurality of computing devices that can receive power from a plurality of power supplies (132 a, 132 b). Each computing device represents a computing component such as a storage device, a blower, a blade server (124), or other power consuming computing component of the computing system (102).

The computing devices depicted in FIG. 1 can receive power from a plurality of power supplies (132 a, 132 b). Each power supply (132 a, 132 b) in FIG. 1 is a device that supplies electric power to an electrical load. Each power supply (132 a, 132 b) may be embodied, for example, as a switched mode power supply that transfers power from a source such as mains power to a load such as the computing devices, while converting voltage and current characteristics.

The computing system (102) of FIG. 1 is depicted as a chassis environment. A ‘chassis environment,’ as the term is used in this specification, refers generally to a blade server system. The blade server system in the example depicted in FIG. 1 is installed in a two-bay chassis (104, 106) and includes one or more of blade servers (124), one or more system management modules (152), one or more media trays (122), and one or more power supplies (132 a, 132 b). The computing system (102) of FIG. 1 therefore includes a plurality of computing devices, illustrated in this example as blade servers (124), the system management module (152), and the media tray (122), although readers will appreciate that in other embodiments additional computing devices may be included in the computing system (102), where each additional computing device can be embodied as any power consuming computing component of the chassis environment.

The system management module (152) of FIG. 1 may be embodied as a computer, including software and hardware components, one or more computer processors and computer memory, that provides system management functions for components in the example chassis environment, including the blade servers (124) and the media tray (122). The system management module (152) of FIG. 1 may also make available connections for user input devices such as mice or keyboards (181) that are not generally connected directly to the blade servers (124) or to the chassis itself.

The computing system (102) of FIG. 1 also includes one or more blade servers (124). The one or more blade servers (124) of FIG. 1 are installed in cabinet bay (104) of the example computing system (102). Such blade servers (124) are computing devices implemented in blade form factor. The blade servers (124) may share access to the media tray (122) and may be connected to one another and to the system management module (152) for data communications through a local area network (‘LAN’) (101), which may be embodied as a small network installed within the computing system (102).

The computing system (102) of FIG. 1 also includes one or more media trays (122). The one or more media trays (122) in FIG. 1 may house non-volatile memory media generally. A media tray (122) may typically include Compact Disc read-only media drives (‘CD-ROM’), Digital Video Disc ROM drives (DVD-ROM), CD-RW drives, DVD-RW drives, floppy disk drives, and so on as will occur to those of skill in the art.

The arrangement of the chassis environment, network (101), and other devices making up the example computing system (102) illustrated in FIG. 1 are for explanation, not for limitation. Computing systems useful according to various embodiments of the present invention may include additional servers, routers, and other devices, not shown in FIG. 1, as will occur to those of skill in the art. Networks in such data processing systems may support many data communications protocols, including Transmission Control Protocol (‘TCP’), Internet Protocol (IP), HyperText Transfer Protocol (‘HTTP’), Wireless Access Protocol (‘WAP’), Handheld Device Transport Protocol (‘HDTP’), and others as will occur to those of skill in the art. Various embodiments of the present invention may be implemented on a variety of hardware platforms in addition to those illustrated in FIG. 1.

For further explanation, FIG. 2 sets forth a block diagram of automated computing machinery comprising an example computer (252) useful in managing computing devices in a computing system according to embodiments of the present invention. The computer (252) of FIG. 2 includes at least one computer processor (256) or ‘CPU’ as well as random access memory (268) (‘RAM’) which is connected through a high speed memory bus (266) and bus adapter (258) to processor (256) and to other components of the computer (252).

Stored in RAM (268) is an image processing module (226), a module of computer program instructions for managing computing devices in a computing system according to embodiments of the present invention. The image processing module (226) may be configured to manage computing devices in a computing system by receiving image data from a plurality of image sensors, identifying one or more characteristics of the computing system in dependence upon the image data from the plurality of image sensors, and initiating one or more desired system management actions in dependence upon the one or more characteristics of the computing system as described in greater detail below.

Also stored in RAM (268) is an operating system (254). Operating systems useful managing computing devices in a computing system according to embodiments of the present invention include UNIX™, Linux™, Microsoft XP™, AIX™, IBM's i5/OS™, and others as will occur to those of skill in the art. The operating system (254) and the image processing module (226) in the example of FIG. 2 are shown in RAM (268), but many components of such software typically are stored in non-volatile memory also, such as, for example, on a disk drive (270).

The computer (252) of FIG. 2 includes disk drive adapter (272) coupled through expansion bus (260) and bus adapter (258) to processor (256) and other components of the computer (252). Disk drive adapter (272) connects non-volatile data storage to the computer (252) in the form of disk drive (270). Disk drive adapters useful in computers for managing computing devices in a computing system according to embodiments of the present invention include Integrated Drive Electronics (‘IDE’) adapters, Small Computer System Interface (‘SCSI’) adapters, and others as will occur to those of skill in the art. Non-volatile computer memory also may be implemented for as an optical disk drive, electrically erasable programmable read-only memory (so-called ‘EEPROM’ or ‘Flash’ memory), RAM drives, and so on, as will occur to those of skill in the art.

The example computer (252) of FIG. 2 includes one or more input/output (‘I/O’) adapters (278). I/O adapters implement user-oriented input/output through, for example, software drivers and computer hardware for controlling output to display devices such as computer display screens, as well as user input from user input devices (281) such as keyboards and mice. The example computer (252) of FIG. 2 includes a video adapter (209), which is an example of an I/O adapter specially designed for graphic output to a display device (280) such as a display screen or computer monitor. Video adapter (209) is connected to processor (256) through a high speed video bus (264), bus adapter (258), and the front side bus (262), which is also a high speed bus.

The example computer (252) of FIG. 2 includes a communications adapter (267) for data communications with other computers (282) and for data communications with a data communications network (200). Such data communications may be carried out serially through RS-232 connections, through external buses such as a Universal Serial Bus (‘USB’), through data communications networks such as IP data communications networks, and in other ways as will occur to those of skill in the art. Communications adapters implement the hardware level of data communications through which one computer sends data communications to another computer, directly or through a data communications network. Examples of communications adapters useful for managing computing devices in a computing system according to embodiments of the present invention include modems for wired dial-up communications, Ethernet (IEEE 802.3) adapters for wired data communications network communications, and 802.11 adapters for wireless data communications network communications.

For further explanation, FIG. 3 sets forth an example of aggregated image data (308) captured from a plurality of image sensors according to embodiments of the present invention. The aggregated image data (308) represents image data created by combining image data captured from a plurality of image sensors. The example depicted in FIG. 3 includes first image data (302) that is captured by a first image sensor (not shown) and second image data (304) that is captured by a second image sensor (not shown). In such an example, using image processing techniques the two images may be compared to identify overlapping image data (306). The overlapping image data (306) represents a portion of each image that has been identified as containing image data of the same computing devices or objects in the computing system. Because each set of image data (302, 304) includes overlapping image data (306), the two sets of image data (302, 304) can be overlaid to produce aggregated image data (308) that provides a more complete view of the computing system.

For further explanation, FIG. 4 sets forth a flow chart illustrating an example method for managing computing devices (402, 404) in a computing system (400) according to embodiments of the present invention. The example method depicted in FIG. 4 is carried out, at least in part, by an image processing module (430). The image processing module (430) depicted in FIG. 4 may be embodied, for example, as a module of computer program instructions executing on computer hardware such as a computer processor. The image processing module (430) may reside on dedicated computer hardware in the computing system (400) such as a server that carries out system management operations. As such, the image processing module (430) may reside on a computing device that is itself part of the computing system (400). Readers will appreciate that in other embodiments the image processing module (430) may reside on computer hardware that is external to the computing system (400).

The example method depicted in FIG. 4 can include receiving (422), by the image processing module (430), image data (414, 416, 418, 420) from a plurality of image sensors (406, 408, 410, 412). Each image sensor (406, 408, 410, 412) depicted in FIG. 4 may be embodied as a computing device that detects and conveys information that constitutes an image, for example, by converting the variable attenuation of waves such as light or electromagnetic radiation into signals. Examples of such image sensors (406, 408, 410, 412) can include semiconductor charge-coupled devices (‘CCDs’), active pixel sensors, as well as image sensors configured to capture video images, infrared sensors, and so on.

Each image sensor (406, 408, 410, 412) depicted in FIG. 4 is coupled to one of the computing devices (402, 404) in the computing system (400). Each image sensor (406, 408, 410, 412) may be mounted on a particular computing device (402, 404) or otherwise mounted proximate to a particular computing device (402, 404). For example, the image sensor (406, 408, 410, 412) may be attached to an enclosure of a particular computing device (402, 404), the image sensor (406, 408, 410, 412) may be attached to another physical structure within a particular computing device (402, 404), the image sensor (406, 408, 410, 412) may be attached to a mounting apparatus such as a chassis at a location that is physically proximate to the particular computing device (402, 404), and so on.

Each image sensor (406, 408, 410, 412) may be coupled to the particular computing device (402, 404) via an I/O interface such as a USB port, such that images captured by the image sensor (406, 408, 410, 412) may stored locally in memory the resides within the computing device (402, 404) that the image sensor (406, 408, 410, 412) is mounted on. In an alternative embodiment, images captured by the image sensor (406, 408, 410, 412) may be transferred to and stored in memory that resides on another computing device. Ultimately, the images captured by the image sensor (406, 408, 410, 412) may be transferred to the image processing module (430). Readers will appreciate that in other embodiments, an image sensor (406, 408, 410, 412) may mounted upon a mounting apparatus such as a rack and that the image sensors (406, 408, 410, 412) may be communicatively coupled directly to the image processing module (430) via means other than one of computing devices (402, 404) in the computing system (400).

In the example depicted in FIG. 4, multiple image sensors (406, 408, 410, 412) may be coupled to each computing device (402, 404) in the computing system (400). For example, two image sensors (406, 408) are coupled to a first computing device (402) and two additional image sensors (410, 412) are coupled to a second computing device (404). Image data (414, 416, 418, 420) may therefore be received from image sensors (406, 408, 410, 412) coupled to different computing devices (402, 404) in the computing system (400). For example, image data (414, 416) is received from image sensors (406, 408) coupled to a first computing device (402) and image data (418, 420) is also received from image sensors (410, 412) coupled to a second computing device (404).

Readers will appreciate that in other embodiments, additional image sensors may be coupled to each of the computing devices (402, 404). For example, a particular computing device (402) may include a forward facing image sensor that is mounted on the front of the computing device (402), a rear facing image sensor that is mounted on the back of the computing device (402), an interior facing image sensor that is mounted so as to capture the interior of the computing device (402), and so on. Readers will further appreciate that computing systems (402) can include additional computing devices, each of which may include image sensors.

Readers will further appreciate that each of the image sensors (406, 408, 410, 412) may be configured to periodically capture image data (414, 416, 418, 420) according to any number of predefined policies. For example, each of the image sensors (406, 408, 410, 412) may be configured to capture image data (414, 416, 418, 420) upon the expiration of a predetermined interval, each of the image sensors (406, 408, 410, 412) may be configured to capture image data (414, 416, 418, 420) according to a predetermined schedule, each of the image sensors (406, 408, 410, 412) may be configured to capture image data (414, 416, 418, 420) when the associated computing device reboots, and so on. In addition, each of the image sensors (406, 408, 410, 412) may include motion detection capabilities such that the image sensors (406, 408, 410, 412) are configured to capture image data (414, 416, 418, 420) upon detecting motion. In such an embodiment, each of the image sensors (406, 408, 410, 412) may be configured to switch modes (e.g., switch from capturing still images to capturing video data) upon detecting motion.

In the example method depicted in FIG. 4, include receiving (422) image data (414, 416, 418, 420) from a plurality of image sensors (406, 408, 410, 412) may be carried out, for example, by the image processing module (430) receiving one or more messages over a data communications network, where each message includes image data (414, 416, 418, 420) from one or more image sensors (406, 408, 410, 412). The image data (414, 416, 418, 420) may be included in a file that adheres to a predetermined format such as the Camera Image File Format (‘CIFF’), a raw image file format, a Joint Photographic Experts Group (‘JPEG’) format, a video file format, and so on.

The example method depicted in FIG. 4 can also include identifying (424), by the image processing module (430) in dependence upon the image data (414, 416, 418, 420) received from the plurality of image sensors (406, 408, 410, 412), one or more characteristics (426) of the computing system (400). The one or more characteristics (426) of the computing system (400) may include information describing, for example, the relative location of computing devices (402, 204) within the computing system (400), the state of one or more computing components of a particular computing device (402, 404) in the computing system (400), the computing devices (402, 404) in the computing system (400) that a particular computing device (402, 404) is coupled to, and so on.

In the example method depicted in FIG. 4, identifying (424) one or more characteristics (426) of the computing system (400) in dependence upon the image data (414, 416, 418, 420) received from the plurality of image sensors (406, 408, 410, 412) may be carried out by extracting information about the computing system (400) from the image data (414, 416, 418, 420) using one or more image processing techniques. For example, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify Quick Response Code (‘QR code’) stickers affixed to a particular computing device (402, 404) whose image was captured by one or more of the image sensors (406, 408, 410, 412), image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify bar code affixed to a particular computing device (402, 404) whose image was captured by one or more of the image sensors (406, 408, 410, 412), and so on.

The image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may also be processed to identify the operational state of components of a particular computing device (402, 404) whose image was captured by one or more of the image sensors (406, 408, 410, 412). For example, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify fans on a particular computing device (402, 404) that are or are not moving, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify doors on a particular computing device (402, 404) that closed. Similarly, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify cables running between two particular computing devices (402, 404) that indicate that the two computing devices (402, 404) are communicatively coupled, and so on.

The example method depicted in FIG. 4 can also include initiating (428), by the image processing module (430) in dependence upon the one or more characteristics (426) of the computing system (400), one or more desired system management actions. A system management action can include actions that impact the operation of the computing devices (402, 404) in the computing system (400). A system management operation can include, for example, turning off a particular computing device (402, 404), altering the manner in which workloads are distributed amongst the computing devices (402, 404), and so on.

Consider an example in which the image data (414, 416, 418, 420) received from the plurality of image sensors (406, 408, 410, 412) indicated that a particular fan on a particular computing device (402) was not operational. In such an example, initiating (428) one or more desired system management actions may include increasing the percentage of workloads that are directed to another computing device (404) while decreasing the percentage of workloads that are directed to the computing device (402) whose fan is inoperable and therefore less capable of performing cooling operations. In such an example, initiating (428) one or more desired system management actions may also include notifying a system administrator that the fan is inoperable, submitting a help request to a centralized repository, and so on.

The example depicted in FIG. 4 illustrates four image sensors (406, 408, 410, 412) mounted on two computing devices (402, 404). Readers will appreciate that embodiments of the present invention may include many additional computing devices and many additional image sensors mounted thereon. For example, a first set of image sensors may be mounted on a first set of computing devices in a first rack in a datacenter, a second set of image sensors may be mounted on a second set of computing devices in a second rack in the datacenter, a third set of image sensors may be mounted on a third set of computing devices in a third rack in the datacenter, and so on. As such, image data may be captured by each set of image sensors that includes images of computing devices in other racks in the datacenter. For example, the first set of image sensors in the first rack may capture images of the computing devices in the second rack, images of the computing devices in the third rack, and so on. Likewise, the second set of image sensors in the second rack may capture images of the computing devices in the first rack, images of the computing devices in the third rack, and so on. By collating all of these images, the image processing module (430) may create a single virtual picture of all of the computing devices in all of the racks of a datacenter. Because the system management module that manages the image sensors and the computing devices in a particular rack has an inventory of the computing devices (e.g., servers, fans, CPUs, network cards) that are located within the particular rack that is managed by the system management module, the single virtual picture can be utilized by a particular system management module to determine where each rack is located relative to each other rack in the datacenter, to determine where each computing device mounted in a particular rack is located relative to each other computing devices mounted within the same rack, to determine where each computing device mounted in a particular rack is located relative to other computing devices mounted in other racks in the datacenter, and so on.

For further explanation, FIG. 5 sets forth a flow chart illustrating an additional example method for managing computing devices (402, 404) in a computing system (400) according to embodiments of the present invention. The example depicted in FIG. 5 is similar to the example depicted in FIG. 4, as the example depicted in FIG. 5 also includes receiving (422) image data (414, 416, 418, 420) from a plurality of image sensors (406, 408, 410, 412), identifying (424) one or more characteristics (426) of the computing system (400), and initiating (428) one or more desired system management actions.

In the example method depicted in FIG. 5, identifying (424) one or more characteristics (426) of the computing system (400) can include identifying (502) one or more computing devices located in a physical hotspot in the computing system (400). A physical hotspot represents an area of the computing system (400) where computing devices (402, 404) tend to operate at higher temperatures. Such a physical hotspot may exist, for example, because hot air rises and thereby causes the ambient temperature at the top of computing rack to be higher than the ambient temperature at the bottom of a computing rack. Likewise, because there is a higher concentration of heat-producing computing devices at a first area of the computing system (400) relative to a second area of the computing system (400), because there is a higher concentration of heat-reducing components such as a fan at first area of the computing system (400) relative to a second area of the computing system (400), and so on.

In the example method depicted in FIG. 5, identifying (502) one or more computing devices located in a physical hotspot in the computing system (400) may be carried out, for example, by aggregating image data (414, 416, 418, 420) from a plurality of image sensors (406, 408, 410, 412). In such an example, the image data (414) from a first image sensor (406) may be compared to the image data (416) from a second image sensor (416) to determine whether any portion of the image data (414, 416) contains identical information that can be used to overlay the image data (414, 416) from the two image sensors (414, 416) to create a more complete view of the computing system (400), as illustrated above with reference to FIG. 3. In such a way, the image processing module (430) may examine an image of the entire computing system to identify areas that are heavily concentrated with heat producing computing devices, to identify areas that are heavily concentrated with heat dissipating computing devices, to identify areas that are further away from vents, and so on. Once the physical hotspots within the computing system (400) have been identified, the image processing module (430) may utilize image data to read a bar code that is affixed to a particular computing device that is located within the a hotspot, the image processing module (430) may utilize image data to read a QR code that is affixed to a particular computing device that is located within the a hotspot, or the image processing module (430) may utilize other techniques to obtain the identity of the computing devices that are located within the physical hotspots.

In the example method depicted in FIG. 5, initiating (428) one or more desired system management actions can include allocating (506) workloads to the computing devices (402, 404) in the computing system (400) in dependence upon which computing devices are located in the physical hotspot. In such an example, a higher percentage of workloads may be allocated to those computing devices that are not located in the physical hotspot relative to the percentage of workloads that are allocated to those computing devices that are located in the physical hotspot. In such a way, a workload distribution module may receive a list of computing devices that are located in the physical hotspot from the image processing module (430), and may allocate workloads utilizing such information.

In the example method depicted in FIG. 5, identifying (424) one or more characteristics (426) of the computing system (400) can alternatively include identifying (504) an operational state of one or more computing components of a particular computing device (402). The operational state of a particular computing component may indicate, for example, that the computing component is malfunctioning, that the computing component is being used improperly, that the computing component is coupled to other computing components, and so on. For example, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify fans on a particular computing device (402, 404) that are or are not moving, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify doors on a particular computing device (402, 404) that are open or closed, image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) may be processed to identify cables running between two particular computing devices (402, 404) that indicate that the two computing devices (402, 404) are communicatively coupled, and so on.

In the example method depicted in FIG. 5, initiating (428) one or more desired system management actions can alternatively include allocating (508) workloads in dependence upon the operational state of one or more computing components of the particular computing device (402). Allocating (508) workloads in dependence upon the operational state of one or more computing components of the particular computing device (402) may be carried out, for example, by allocating workloads only to those computing devices whose heat-dissipating components (e.g., a fan) are operational, by allocating workloads only to those computing devices whose doors are closed as an open door may indicate that the computing device is being serviced, by allocating workloads that operate on highly confidential information only to those servers that are not connected to other servers in an attempt to increase security, and so on.

For further explanation, FIG. 6 sets forth a flow chart illustrating an additional example method for managing computing devices (402, 404) in a computing system (400) according to embodiments of the present invention. The example depicted in FIG. 6 is similar to the example depicted in FIG. 4, as the example depicted in FIG. 6 also includes receiving (422) image data (414, 416, 418, 420) from a plurality of image sensors (406, 408, 410, 412), identifying (424) one or more characteristics (426) of the computing system (400), and initiating (428) one or more desired system management actions.

In the example method depicted in FIG. 6, identifying (424) one or more characteristics (426) of the computing system (400) can include determining (602) an identity of one or more of the computing devices (402, 404) in the computing system (400). In the example method depicted in FIG. 6, determining (602) the identity of one or more of the computing devices (402, 404) in the computing system (400) may be carried out, for example, by extracting an identifier of the computing device from a bar code affixed to the computing device (400) from image data (414, 416, 418, 420) from one or more of the image sensors (406, 408, 410, 412), by extracting an identifier of the computing device from a QR code affixed to the computing device (400) from image data (414, 416, 418, 420) from one or more of the image sensors (406, 408, 410, 412), and so on.

In an alternative embodiment, determining (602) an identity of one or more of the computing devices (402, 404) in the computing system (400) may be carried out by the image processing module (430) initiating a request for a particular device to illuminate one or more of its indicator lights, the image sensors (406, 408, 410, 412) capturing image data (414, 416, 418, 420), and the image processing module (430) examining the image data (414, 416, 418, 420) to identify the computing device in the computing system (400) whose indicators light are illuminated as requested. In such a way, the network address or other identifier of computing device that received the request to illuminate one or more of its indicator lights may used as the identity of the computing device, whose relative location can be ascertained from the image data (414, 416, 418, 420).

In the example method depicted in FIG. 6, initiating (428) one or more desired system management actions can include performing (604) a system inventory check. A system inventory check may be performed (604) by comparing the identities of each computing device captured through the use of the image sensors (406, 408, 410, 412) to a list or other data structure that identifies all computing devices that are expected to be in the computing system (400). In such a way, missing computing devices may be discovered or computing devices that are not intended to be in the computing system (400) may be identified, such as computing devices that were erroneously installed in the computing system (400).

In the example method depicted in FIG. 6, initiating (428) one or more desired system management actions can also include notifying (606) a system administrator of any discrepancies discovered in the system inventory check. The system administrator may be notified (606), for example, by reporting the discrepancy between the detected devices and the expected devices to a system administration module, by generating an error message that includes the discrepancy between the detected devices and the expected devices to a system administration module, and so on.

For further explanation, FIG. 7 sets forth a flow chart illustrating an additional example method for managing computing devices (402, 404) in a computing system (400) according to embodiments of the present invention.

In the example method depicted in FIG. 7, identifying (424) one or more characteristics (426) of the computing system (400) can include constructing (702) a map (704) of the computing system (400). In the example method depicted in FIG. 7, the map (704) of the computing system (400) may be embodied as a data structure that includes, for example, the relative location of each computing device (402, 404) in the computing system (400), the coordinate location of each computing device (402, 404) in the computing system (400) relative to a fixed point, information identifying connectivity between two or more computing devices (402, 404) in the computing system (400), and so on. Consider the following example of such a map (704), embodied in this example as a table.

In the example method depicted in FIG. 7, constructing (702) the map (704) of the computing system (400) may be carried out by, for each computing device (402, 404) in the computing system (400), identifying (706) the location of the computing device (402, 404) relative to one or more other computing devices (402, 404) in the computing system (400). Identifying (706) the location of a particular computing device (402) relative to one or more other computing devices (404) in the computing system (400) may be carried out, for example, by utilizing image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) to determine the angular relationship between the particular computing device (402) and the one or more other computing devices (404) in the computing system (400) from the perspective of the image sensor (406, 408, 410, 412) that captured the image data (414, 416, 418, 420), by utilizing image data (414, 416, 418, 420) captured by one or more of the image sensors (406, 408, 410, 412) to determine the location on a coordinate plane of the particular computing device (402) relative to the one or more other computing devices (404) in the computing system (400) from the perspective of the image sensor (406, 408, 410, 412) that captured the image data (414, 416, 418, 420), and so on.
